My Soap Service Proxy Codeunit

Up to now we in Advania have been using the method described here on my blog to connect to most of the Soap web services that we needed to integrate with.

The problem with this method is that we have to manage a lot of DLLs.  This has caused some issues and problems.

Another thing is that we are moving to AL.  And in AL we can’t just throw in a custom DLL to do all the work.

In C/AL We can do this with standard dotnet objects

AL code to do the same with the built in AL objects but that code is not much shorter.

With a custom proxy DLL the code would be

With this example we can easily see why we have chosen to create a proxy DLL for most of the Soap services.

I wanted to find a way to make things easier in AL and I remembered having dealt with C/AL objects by Vjeko from some time ago.  I took another look and that code helped me to get started.

The result is a Soap Proxy Client Mgt. Codeunit in C/AL that I have sent to Microsoft’s cal-open-library project asking to have this code put into the standard C/AL library.

Using this Codeunit the code will be like this.

What about AL?

For now this C/AL Codeunit is not in the standard CRONUS database.  I need to import the C/AL code and make sure that AL will be able to use that Codeunit.  You can see how to do this in my last blog post.

This C/AL Code will directly convert to AL and is ready to use.

More examples on how to use this Proxy Codeunit will follow.  Stay tuned…

Using the Translation Service for G/L Source Names

Until now I have had my G/L Source Names extension in English only.

Now the upcoming release of Microsoft Dynamics 365 Business Central I need to supply more languages.  What does a man do when he does not speak the language?

I gave a shout out yesterday on Twitter asking for help with translation.  Tobias Fenster reminded me that we have a service to help us with that.  I had already tried to work with this service and now it was time to test the service on my G/L Source Names extension.

In my previous posts I had created the Xliff translation files from my old ML properties.  I manually translated to my native language; is-IS.

I already got a Danish translation file sent from a colleague.

Before we start; I needed to do a minor update to the AdvaniaGIT tools.  Make sure you run “Advania: Go!” to update the PowerShell Script Package.  Then restart Visual Studio Code.

Off to the Microsoft Lifecycle Services to utilize the translation service.

Now, let’s prepare the Xliff files in Visual Studio Code.  From the last build I have the default GL Source Names.g.xlf file.  I executed the action to create Xliff files.

This action will prompt for a selection of language.  The selection is from the languages included in the NAV DVD.

After selection the system will prompt for a translation file that is exported from FinSql.  This I already showed in a YouTube Video.  If you don’t have a file from FinSql you can just cancel this part.  If you already have an Xliff file for that language then it will be imported into memory as translation data and then removed.

This method is therefore useful if you want to reuse the Xliff file data after an extension update.  All new files will be based on the g.xlf file.

I basically did this action for all 25 languages.  I already had the is-IS and da-DK files, so they where updated.  Since the source language is en-US all my en-XX files where automatically translated.  All the other languages have translation state set to “needs-translation”.

All these files I need to upload to the Translation Service.  From the Lifecycle Services menu select the Translation Service.  This will open the Translation Service Dashboard.

Press + to add a translation request.

I now need to zip and upload the nl-NL file from my Translations folder.

After upload I Submit the translation request

The request will appear on the dashboard with the status; Processing.  Now I need to wait for the status to change to Completed.  Or, create requests for all the other languages and upload files to summit.

When translation has completed I can download the result.

And I have a translation in state “needs-review-translation”.

Now I just need to complete all languages and push changes to GitHub.

Please, if you can, download your language file and look at the results.

Upgrading my G/L Source Names Extension to AL – step 4 addendum

In the last blog post we completed the translation to our native language.  Since then I have learned that I also need to include translation files for EN-US, EN-GP and EN-CA.

With the latest update of AdvaniaGIT tools that was an easy task.  Just asked to create Xlf file for these languages and skipped the part where we import C/AL translation.

I have also been pointed to a new tool that can work with Xlf files.  Multilingual Editor: https://marketplace.visualstudio.com/items?itemName=MultilingualAppToolkit.MultilingualAppToolkitv40

Now I call out to all who are ready to help me with the translation.  Please fork my NAV2018 repository and send me Xlf translation files for your native language.  Or just download one of the translation files and send me your language.

Our next step is to code sign the App file and send it to Microsoft.

Upgrading my G/L Source Names Extension to AL – step 4

We are on a path to upgrade G/L Source Names from version 1 to version 2.  This requires conversion from C/AL to AL, data upgrade and number of changes to the AL code.

A complete check list of what you need to have in your AL extension is published by Microsoft here.

Our task for today is to translate the AL project into our native language.

To make this all as easy as I could I added new functionality to the AdvaniaGIT module and VS Code extension.  Make sure to update to the latest release.

To translate an AL project we need to follow the steps described by Microsoft here.

To demonstrate this process I created a video.

 

Upgrading my G/L Source Names Extension to AL – step 3

When upgrading an extension from C/AL to AL (version 1 to version 2) we need to think about the data upgrade process.

In C/AL we needed to add two function to an extension Codeunit to handle the installation and upgrade.  This I did with Codeunit 70009200.  One function to be execute once for each install.

And another function to be executed once for each company in the install database.

For each database I add my permission sets to the installation users and for each company I restore the setup data for my extension and populate the lookup table for G/L Source Name.

The methods for install and upgrade have changed in AL for extensions version 2.  Look at the AL documentation from Microsoft for details.

In version 2 I remove these two obsolete function from my application management Codeunit and need to add two new Codeunits, one for install and another for upgrade.

In the code you can see that this Codeunit is of Subtype=Install.  This code will  be executed when installing this extension in a database.

To confirm this I can see that I have the G/L Source Names Permission Sets in the Access Control table .

And my G/L Source Name table also has all required entries.

Uninstalling the extension will not remove this data.  Therefore you need to make sure that the install code is structured in a way that it will work even when reinstalling.  Look at the examples from Microsoft to get a better understanding.

Back to my C/AL extension.  When uninstalling that one the data is moved to archive tables.

Archive tables are handled with the NAVAPP.* commands.  The OnNavAppUpgradePerCompany command here on top handled these archive tables when reinstalling or upgrading.

Basically, since I am keeping the same table structure I can use the same set of commands for my upgrade Codeunit.

So, time to test how and if this works.

I have my AL folder open in Visual Studio Code and I use the AdvaniaGIT command Build NAV Environment to get the new Docker container up and running.

Then I use Update launch.json with current branch information to update my launch.json server settings.

I like to use the NAV Container Helper from Microsoft  to manually work with the container.  I use a command from the AdvaniaGIT module to import the NAV Container Module.

The module uses the container name for most of the functions.  The container name can be found by listing the running Docker containers or by asking for the name that match the server used in launch.json.

I need my C/AL extension inside the container so I executed

Then I open PowerShell inside the container

Import the NAV Administration Module

and I am ready to play.  Install the C/AL extension

Now I am faced with the fact that I have opened PowerShell inside the container in my AdvaniaGIT terminal.  That means that my AdvaniaGIT commands will execute inside the container, but not on the host.

The simplest way to solve this is to open another instance of Visual Studio Code.  From there I can start the Web Client and complete the install and configuration of my C/AL extension.

I complete the Assisted Setup and do a round trip to G/L Entries to make sure that I have enough data in my tables to verify that the data upgrade is working.

I can verify this by looking into the SQL tables for my extension.  I use PowerShell to uninstall and unpublish my C/AL extension.

I can verify that in my SQL database I now have four AppData archive tables.

Pressing F5 in Visual Studio Code will now publish and install the AL extension, even if I have the terminal open inside the container.

The extension is published but can’t be installed because I had previously installed an older version of my extension.  Back in my container PowerShell I will follow the steps as described by Microsoft.

My AL extension is published and I have verified in my SQL server that all the data from the C/AL extension has been moved to the AL extension tables and all the archive tables have been removed.

Back in Visual Studio Code I can now use F5 to publish and install the extension again if I need to update, debug and test my extension.

Couple of more steps left that I will do shortly.  Happy coding…

 

Upgrading my G/L Source Names Extension to AL – step 2

So, where is step 1?  Step 1 was converting C/AL code to AL code.  This we did with AdvaniaGIT and was demonstrated here.

First thing first!  I received the following email from Microsoft.

Hello,

The decision has been made by our SLT, that the use of a Prefix or Suffix is now a mandatory requirement. If you are already using this in your app(s), great. If not, you will want to do so.

We are coming across too many collisions between apps in our internal tests during builds and have seen some in live tenants as well. It makes the most sense to make this a requirement now. If you think about it in a live situation, if a customer installs an app before yours and then tries yours but gets collision issues, they may just decide to not even continue on with yours.

Also, I have been made aware that adding a prefix or suffix after you already have a v2 app published can make the process complicated for you. Therefore, since you all have to convert to v2 anyway, now is a good time to add in the prefix/suffix.

The following link provides the guidelines around using it here

If you haven’t reserved your prefix yet, please email me back to reserve one (or more if needed).

Thank you,

Ryan

Since my brand is Objects4NAV.com I asked for 04N as my prefix and got it registered.  Since we got this information from Microsoft, every object that we develop in NAV 2018 now has our companies prefix in the name.

Starting my AL development by opening Visual Studio Code in my repository folder.  I updated my setup.json to match the latest preview build as Docker container and then selected to Build NAV Environment using AdvaniaGIT.

After download and deployment of the container I noticed that the container had a brand new version of the AL Extension for Visual Studio Code.  I looked at the version installed and that was an older version.

I uninstalled the AL Language extension and restarted Visual Studio Code.

As you can see on the screenshot above we now don’t have any AL Language extension installed.  I executed the Build NAV Environment command from AdvanaiGIT to install the extension on the Docker container.  In this case I already had a container assigned to my branch so only three things happened.

  • uidOffset in the container database was updated.  This is recommended for C/AL development.
  • License file is updated in the container database and container service.  The license used is the one configured in branch setup.json or the machine settings GITSettings.json
  • AL Language Extension is copied from the container to the host and installed in Visual Studio Code.

Again, restarting Visual Studio Code to find that the latest version of AL Language Extension has been installed.

I then executed two AdvaniaGIT actions.

  • Update Launch.json with current branch environment.  This will update the host name and the service name in my AL Launch.json file to make sure that my AL project will be interacting with the branch container.
  • Open Visual Studio Code in AL folder.  This will open another instance of Visual Studio Code in the AL folder.

Immediately after Visual Studio Code was opened it asked for symbols and I agreed that we should download them from the container.

Everything is now ready for AL development using the latest build that Microsoft has to offer.

I started  Edit – Replace in Files in Visual Studio Code.  All my objects have a name that start with G/L Source Name.  I used this knowledge to apply the prefix.

By starting with the double quote I make sure to only update the object names and not captions.  All captions start with a single quote.  I got a list of all changes and needed to confirm all changes.

The field name I add to G/L Entry table does not match this rule so I needed to rename that my self.  Selecting the field name and pressing F2 allows me to rename a field and have Visual Studio Code update all references automatically.

Pressing F5 started my build, publish and debug.

My extension is installed and ready for testing.

There are a few more steps that I need to look into before publishing the new version of G/L Source Names to Dynamics 365.  These steps will appear here in the coming days.  Hope this will be useful to you all.

Using AdvaniaGIT – Convert G/L Source Names to AL

Here we go.

The NAV on Docker environment we just created can be used for the task at hand.  I have an Extension in Dynamics 365 called G/L Source Names.

I need to update this Extension to V2.0 using AL.  In this video I go through the upgrade and conversion process using AdvainaGIT and Visual Studio Code.

In the first part I copy the deltas from my Dynamics 365 Extension into my work space and I download and prepare the latest release of NAV 2018 Docker Container.

Using our source and modified environments we can build new syntax objects and new syntax deltas. These new syntax deltas are then converted to AL code.

 

Working with optional NAV table fields

Now that we have entered the Extension era we must take into account that some extensions may or may not be installed at the time of code execution.

You might even have two Extensions that you would like to share data.

Let’s give an example.

In Iceland we add a new field to the Customer table (18).  That field is named “Registration No.” and is being used for a 10 digit number that is unique for the individual or the company we add as a customer to your system.

My Example Extension can support Icelandic Registration No. if it exists.

Using Codeunit 701, “Data Type Management”, Record Reference and Field Reference we can form the following code.

Let’s walk through this code…

GetRecordRef will populate the record reference (RecRef) for the given table and return TRUE if successful.
FindFieldByName will populate the field reference (FltRef) for the given record reference and field name and return TRUE if successful.

Call this function with a code like this.

We could create a more generic function.

This function can be used in more generic ways, like

See where I am going with this?

So the other way around…

And using this with

More generic versions can be something like this.

To use these functions we first need to copy our record to a variant variable and then back to the record after the function completes.

Or

I have requested Microsoft to add more generic functions to Codeunit 701, “Data Type Management”.  I trust that they will deliver as usual.

That NAV Codeunit is one of my favorite ones delivered by Microsoft.
